Killer royal aide Jane Andrews has failed in her bid for freedom... ­because she is still considered too dangerous.

Fergie’s former dresser, who battered and stabbed her boyfriend to death after her refused to marry her, had been eligible for release after serving 12 years of a life sentence.

But the Parole Board ruled she should not be let out as she ­remains a danger to the public.

Andrews, 44, is ­understood to have shown no remorse for the brutal murder of Mr Cressman, whose sister Cathy spoke to the members of the board to tell them of the impact his murder had on their family.

She also began ­writing a series of ­obsessive letters to a married father of two while in prison.

And her cause won’t have been helped when she absconded from East Sutton Park open women’s prison in Kent three years ago. She was found three days later in a hotel six miles away, where she had been joined by her parents.

A source said: “Andrews wasn’t at all happy because she was convinced she was going to be released.

“But the fact that she clearly still has obsessive tendencies didn’t help her convince the Parole Board that she wasn’t a ­danger.

“The lack of remorse is also an indicator that she may still be a danger and was taken into ­consideration. The views of the ­victim’s family are obviously heard, but the final barometer of whether somebody should be released is if they are deemed a danger. Clearly Andrews did not pass that test.”

Andrews is expected to be ­eligible for parole again next year.

Andrews, the daughter of a joiner and a social workers from Cleethorpes, Lincolnshire, worked for the ­Duchess of York for nine years, joining her on royal duties both at homeand abroad.

Earlier this year the Sunday Mirror told how she had become obsessed with father-of-two Mark Ellson, sending him letters marked “to my husband”. She wrote to him seven years ago while he was serving time for fraud after ­reading about him in a prison newspaper.

They began a correspondence and Mark visited her in jail after he had been released. But he broke off contact when her letters started to ­become obsessive. It was his failure to turn up for a visit in 2009 that saw her go on the run from jail.

After hearing nothing from her for many months, Mark ­received a ­series of cards from Andrews earlier this year.

In one she had ­super­imposed pictures of hers and Mark’s heads on to a picture of David ­Walliams and James Cracknell in wetsuits, adding the message “What asexy pair!”

Mark has said: “It’s important people get to know the real Jane Andrews before she is released. She has latched on to me ­because I’ve shown an interest in her. She then takes it too far and becomes obsessive. I can see how erratic she can be.”

A Parole Board spokesman said: “Once a life-sentence prisoner’s minimum tariff has been served, the only legal question which has to be answered is whether or not the prisoner is a risk to the public.”
